The Docker API is an HTTP REST API served by Docker Engine. It is the API the Docker client uses to communicate with the Engine, so everything the Docker client can do can be done with the API.
Most of the client's commands map directly to API endpoints (e.g. `docker ps` is `GET /containers/json`). The notable exception is running containers, which consists of several API calls. [There is example of using `curl` to run a container in the SDK documentation.](#TODO)
# Errors
The Remote API uses standard HTTP status codes to indicate the success or failure of the API call. The body of the response will be JSON in the following format:
```
{
"message": "page not found"
}
```
# Versioning
The API is usually changed in each release of Docker. If you want to write a client that doesn't break when connecting to newer Docker releases, you can lock to a specific API version.
For Docker 1.13, the API version is 1.25. To lock to this version, you prefix the URL with `/v1.25`. For example, calling `/info` is the same as calling `/v1.25/info`.
The API uses an open schema model, which means server may add extra properties to responses. Likewise, the server will ignore any extra query parameters and request body properties. When you write clients, you need to ignore additional properties in responses to ensure they do not break when talking to newer Docker daemons.
# Authentication
Authentication for registries is handled client side. The client has to send authentication details to various endpoints that need to communicate with registries, such as `POST /images/(name)/push`. These are sent as `X-Registry-Auth` header as a Base64 encoded (JSON) string with the following structure:
```
{
"username": "string",
"password": "string",
"email": "string",
"serveraddress": "string"
}
```
The `serveraddress` is a domain/IP without a protocol. Throughout this structure, double quotes are required.
If you have already got an identity token from the [`/auth` endpoint](#operation/checkAuthentication), you can just pass this instead of credentials:

/containers/{id}/attach:
post:
summary:"Attach to a container"
description:|
Attach to a container to read its output or send it input. You can attach to the same container multiple times and you can reattach to containers that have been detached.
Either the `stream` or `logs` parameter must be `true` for this endpoint to do anything.
See [the documentation for the `docker attach` command](https://docs.docker.com/engine/reference/commandline/attach/) for more details.
### Hijacking
This endpoint hijacks the HTTP connection to transport `stdin`, `stdout`, and `stderr` on the same socket.
This is the response from the daemon for an attach request:
```
HTTP/1.1 200 OK
Content-Type:application/vnd.docker.raw-stream
[STREAM]
```
After the headers and two new lines, the TCP connection can now be used for raw, bidirectional communication between the client and server.
To hint potential proxies about connection hijacking, the Docker client can also optionally send connection upgrade headers.
For example, the client sends this request to upgrade the connection:
```
POST /containers/16253994b7c4/attach?stream=1&stdout=1 HTTP/1.1
Upgrade:tcp
Connection:Upgrade
```
The Docker daemon will respond with a `101 UPGRADED` response, and will similarly follow with the raw stream:
```
HTTP/1.1 101 UPGRADED
Content-Type:application/vnd.docker.raw-stream
Connection:Upgrade
Upgrade:tcp
[STREAM]
```
### Stream format
When the TTY setting is disabled in [`POST /containers/create`](#operation/PostContainerCreate), the stream over the hijacked connected is multiplexed to separate out `stdout` and `stderr`. The stream consists of a series of frames, each containing a header and a payload.
The header contains the information which the stream writes (`stdout` or `stderr`). It also contains the size of the associated frame encoded in the last four bytes (`uint32`).
`SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size encoded as big endian.
Following the header is the payload, which is the specified number of bytes of `STREAM_TYPE`.
The simplest way to implement this protocol is the following:
1. Read 8 bytes.
2. Choose `stdout` or `stderr` depending on the first byte.
3. Extract the frame size from the last four bytes.
4. Read the extracted size and output it on the correct output.
5. Goto 1.
### Stream format when using a TTY
When the TTY setting is enabled in [`POST /containers/create`](#operation/PostContainerCreate), the stream is not multiplexed. The data exchanged over the hijacked connection is simply the raw data from the process PTY and client's `stdin`.

summary:"Export an image"
description:|
Get a tarball containing all images and metadata for a repository.
If `name` is a specific name and tag (e.g. `ubuntu:latest`), then only that image (and its parents) are returned. If `name` is an image ID, similarly only that image (and its parents) are returned, but with the exclusion of the `repositories` file in the tarball, as there were no image names referenced.
### Image tarball format
An image tarball contains one directory per image layer (named using its long ID), each containing these files:
- `VERSION`:currently `1.0` - the file format version
- `json`:detailed layer information, similar to `docker inspect layer_id`
- `layer.tar`:A tarfile containing the filesystem changes in this layer
The `layer.tar` file contains `aufs` style `.wh..wh.aufs` files and directories for storing attribute changes and deletions.
If the tarball defines a repository, the tarball should also include a `repositories` file at the root that contains a list of repository and tag names mapped to layer IDs.
Get a tarball containing all images and metadata for several image repositories.
For each value of the `names` parameter:if it is a specific name and tag (e.g. `ubuntu:latest`), then only that image (and its parents) are returned; if it is an image ID, similarly only that image (and its parents) are returned and there would be no names referenced in the 'repositories' file for this image ID.
For details on the format, see [the export image endpoint](#operation/GetImage).
